Question 42:

What is keyword stemming?

The process of keyword stemming involves taking a basic but popular keyword pertaining to a particular website and adding a prefix, suffix, or pluralization to make the keyword into a new word. Keyword stemming can help the crawlers find your website and thus increase your traffic.

For example: If "solve" is a keyword you can add "ing" or "ed" to create new keywords like "solved" or "solving"

Question 43:

Name some SEO blogs that you frequently read.

When this question is asked generally interviewer try to check which all popular blogs you refer regularly for updates on SEO. For example, I frequently read blogs of Modern Pathshala Site and Neil Patel. So tell the interviewer which all blogs you generally read rather than stating some unknown famous blogger's site/website which you don't follow.
